Jay Cost

In 2005, while working on his dissertation at the University of Chicago, Cost joined the staff of RealClearPolitics. Cost became a writer for The Weekly Standard in 2010.^[3] Although his education background is in political science, Cost claims that he has come to rely more on his reading of the history of American elections than on political science and public opinion polling.^[6] In 2012 Cost released a book, Spoiled Rotten: How the Politics of Patronage Corrupted the Once Noble Democratic Party and Now Threatens the American Republic, in which Cost argued that the Democratic Party has been taken over by interest groups.^{[7][8][9][10][11]} Barack Obama ultimately won the election, and PPP's Tom Jensen and New York's Jonathan Chait criticized Cost's skepticism of the polls.^[12][13] He left the Republican Party in 2016 when the party refused to prevent Donald Trump from obtaining the nomination at the convention.^[1]
